 When children are between the ages of 8 and 12, parents often ask dermatologists this question. If you’re a parent trying to answer this question, you’ve come to the right place.  In three easy steps, you can figure out how often a child between 8 and 12 years of age needs to shampoo.  Step 1: Consider your child’s traits To determine how often your child needs to shampoo, you first need to consider your child’s: Hair type (straight, curly, oily, dry) Age Activity level Step 2: Find your child’s traits on the following chart Shampoo guidelines: Children 8 to 12 years old Shampoo every other day or daily 12 years of age or starting puberty Oily, straight hair Active: Plays outdoors, plays sports, or swims Exception: Hair is dry and curly Shampoo 1 or 2 times per week 8 to 11 years of age Exception: Hair is dry and curly Shampoo every 7 to 10 days Dry and curly hair, even hair with braids or weaves After heavy sweating or swimming, rinse and condition the hair Step 3: Fine tune to get

Is Breast Cancer Genetic?

 Except for some types of skin cancer, breast cancer is the most common cancer in people assigned female at birth. In this group, the average lifetime risk of developing breast cancer is 13%Trusted Source, according to the American Cancer Society.

Some individuals have a higher chance of breast cancer. This can be due to genetic factors that increase risk.

This article takes a closer look at the genetic and hereditary risk factors for breast cancer and the screening recommendations for those at higher risk.

What are the genetic and hereditary risk factors for breast cancer?

Cancer is a genetic diseaseTrusted Source. It’s caused by DNA changes, called mutations, in certain genes that cause cells to grow and divide out of control.

Most genetic changes that contribute to cancer are acquired during your lifetime. These are called somatic mutations. Somatic mutations happen due to things like the natural aging process or certain lifestyle and environmental factors.

What about hereditary breast cancer?

Hereditary cancer is when cancer runs in families. This means mutations associated with higher cancer risk are passed down to you from one or both of your parents. About 5–10%Trusted Source of breast cancers are hereditary.

The most common hereditary cause of breast cancer is mutations in the BRCA1 or BRCA2 genes. Individuals with BRCA mutations have about a 70% chanceTrusted Source of developing breast cancer by age 80 years. These mutations also increase the risk of:

breast cancer at a younger age

breast cancer affecting both breasts

other cancers, including ovarian and pancreatic cancers

You can inherit BRCA mutations from either parentTrusted Source. If you’re the child of a parent who has a BRCA mutation, you have a 50%Trusted Source chance of inheriting the mutation.

It’s also possible to have breast cancer run in your family but not be associated with any known mutations that increase breast cancer risk. Scientists continue to work to identify and characterize further inherited risk factors for breast cancer.

What other genes are associated with hereditary breast cancer?

Hereditary breast cancer can also result from inherited mutations in other genes. Though these are much less commonTrusted Source.

Some gene mutations are linked with rare genetic syndromes that increase the risk of breast cancer and other cancer types. Gene mutations involved in these syndromes include:

PTEN, which causes Cowden syndrome

TP53, which causes Li-Fraumeni syndrome

CDH1, which causes hereditary diffuse gastric cancer and also increases the risk of lobular breast cancer

 Many treatments that enhance the appearance of your hair can actually damage it, causing your hair to become dry and brittle. Follow these dermatologists’ tips to prevent dry, brittle hair: When dyeing your hair, stay ‘on shade’. Choose a dye within three shades of your natural color. Typically dyeing hair darker is better than lighter. Lightening your hair more than three shades requires higher volumes of peroxide, which causes more hair damage. Test store-bought hair color before using. Follow manufacturer’s instructions. If you develop a rash or redness, swelling, burning or itching, you are having an allergic reaction to the die. Do not dye your hair and consult your dermatologist for further allergy testing. Protect your hair from the sun. The sun can make your hair weak, dry, rough, faded and brittle. This is especially true if you dye, bleach or perm your hair. Wear a wide-brimmed hat when you go outside. Use caution when perming hair to prevent long-lasting damage. Set a timer

Does Breastfeeding Prevent Breast Cancer?

 How does breastfeeding lower your risk of breast cancer? Breastfeeding is a protective factor for breast cancer. It’s unclear exactly why this is the case. However, a combination of the following factors is likely at work: Breastfeeding promotes changes in breast cells that may make breast cancer less likely to occur. The hormonal changes that happen during breastfeeding can delay the return of your period, meaning you’re exposed to less estrogen while breastfeeding. Long-time exposure to estrogen raises breast cancer risk. It’s more likely that people who are breastfeeding engage in healthy lifestyle choices, such as eating a balanced diet, avoiding alcohol, and not smoking. Now let’s look at what some of the research on breastfeeding and breast cancer risk has found. Research into breastfeeding and breast cancer risk Older research from 2002Trusted Source involving data from 47 studies across 30 countries found that the risk of breast cancer decreased by 4.3% for every 12 months of


 Summer activities can do major damage to your hair. A few simple steps can keep your locks looking healthy all summer long. Mother and young daughter having fun in swimming pool. Though it is part of our routines to make sure to protect our skin before heading out for a fun, sun-filled summer day (and every day!), rarely do we give our hair the same attention. From chlorinated swimming pools to the sun’s harmful ultraviolet (UV) rays, our hair experiences heightened stress in the warmest months of the year. To avoid damage and provide protection to our locks, it’s essential to understand the risks and take proactive measures. To keep your hair healthy, silky, and shiny, try these board-certified dermatologist-approved swim season tips. What happens to our hair in the sun Hair, similar to skin, is susceptible to damage from the sun — specifically UV damage, says Dr. Farah Moustafa, MD, FAAD, a board-certified dermatologist and assistant professor and director of laser and cosmetics at
